' EYEGLASSES.

Specification of Letters Patent.

Patented Sept. 21,

Application filedApril 10,-.1909. Serial No. 489,158.

To all whom concern:

Be it known that I, EDWARD F. Mnssinn, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented new and useful Improvements in Eyeglasses of which thefollowing is a specification.

This invention relates to a spring attachment for finger piece mountingin eyeglasses. The object of the invention is to provide a finger piecewhich will swing with practically uniform. pressure. The spring isconcealed and the-pivot can be mounted so as to be secure against,working loose or falling out of place.

This invention is set forth in the follow- 1 line w m Fig. 4.

In this drawing the letter a indicates a lens of an'eye glass. To thelens is secured a barrel or cylinder Z). A finger piece 0 has a-pivot orturning point in the barrel or housing 7). This pivot is shown composedof two pieces 0 for a purpose presently explained. The fin er piece 0can be provided with or connected to a guard (Z adapted to sit againstthe side of the nose. Between the pieces or sections of the pivot e isengaged an one portion of a spiing f. The

other end portion of this spring 7 is engaged by or braced against asuitable portion of barrel or housing 7). The spring is flat so as notto occupy much space.

WVhen the eye glasses are worn each spring tends to press its guard dagainst a side of the nose so as to hold the eye glass firmly inposition on the person. By press ing the finger piece 0 its guard (Z isswung away from the nose as 'required when removing or replacing theglasses. Suitable washers 9 about the pivot 6 close the ends of thebarrel so as to conceal the spring and prevent the same from becomingdisplaced. These washers 9 also serve to maintain the pivot e in steadyposition.

In the use of a spring coiled a number of times about the pivot it hasbeen found that as the finger piece 0 is swung the tension of the coiledspring is considerably increased while the tension of a flat springcoiled not more than once about the pivot remains practically uniform.By the use of a pivot applied as shown herein the danger of the pivotworking loose is avoided as was liable to occur in case a screw was usedfor a pivot. The pivot c or each of I its component parts can besuitably headed or riveted.

I claim 1. An eye glass provided with a barrel, a pivot inclosed in thebarrel and provided with a finger piece and nose grip and a flat springmade to engage the pivot, said pivot being formed of two pieces toreceive the spring therebetween.

2. An eye glass provided with a barrel. a pivot with a spring bothinclosed in the barrel and provided with a finger piece and nose grip,and washers about the pivot. made to close the barrel.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
